SPECIFICATION forming part of Letters Patent No. 262,692, dated August15, 1882.-

Application filed May 5, 1882. (No model.) Patented in England October6,1881,No.4,345; in France April 3, 1882, No.148,246, and in BelgiumApril 11, 1882, No. 57,579.

To all whom it may concern Be itknown that I, JAMES RIGG, of Chester, inthe county of Chester, in the Kingdom of England, have invented certainnew and useful Improvements in Elevators, (for which I have receivedLetters Patent in England, No. 4,345, dated 6th October, 1881,) of whichthe following is a specification.

This invention has for its principal object improvements in coalingsteamers from lighters. It may, however, be also employed for loading ordischarging slack, corn, salt, gravel, clay, 'or other minerals ormaterials of a fragmentary, granular, or pulverulent character.

My apparatus is set forth in the accompanyin g drawings, in which Figure1 is a transverse elevation, partly in section,of the apparatus at worktranshipping coal from a flat into a larger vessel through thedeck-bunkers under a covered alley-way. The covers are, however, notshown in the drawings. Fig. 2 is a longitudinal elevation of same withflat removed; Fig. 3, a plan view of parts shown in Fig. 2 Fig. 4, anend elevation of elevator with frames lowered and stored away fore andaft on the ponton; Fig. 5, a side elevation of same; Fig. 6, a plan ofsame; Figs. 7, 8, 9,10, sectional details, showingapparatus forconveying the coal from the elevators to the bunkers; Figs. 11, 12,13,14, and 15, details of elevator-frames and chains of buckets.

In the drawings, A is a hollow tower or tube placed about centrally upona barge, or preferably two pontons, G G, as shown in the drawings. Ithas a roller-path upon its head and another near the heel or afoot-step, upon which the whole can swivel horizontally, can be usedinstead. These roller-paths bear the weight of the partially-revolvinghead B.

O C are frames suspended by means of blocks b and chains 3, passing overthe pulleys b b b b and round guide-pulleys, (not shown in thedrawings,) Sheet 4, to the barrel of a steam winch or drum,h,'drivenbyapair of winding-engines, Z. This enables the double frame-work O O,carrying the elevator, to be raised or lowered by power.

The lower ends of the double framework 0 (3 may be curved downward, soas to facilitate the loading from barges which may be partially coveredby their decks, as shown in Fig.

1, the chains and buckets also being suitably constructed, as describedhereinafter.

The head upon the tower is made capable of revolving through somewhatmore than a quadrant, and through the intervention of a worm-wheel orother gearing, or in any other well-known manner,the pair ofelevator-frames may be revolved by power.

The elevators are driven by means of an endless wire or other rope, 2,which passes round a pulley upon the steam-winch, as shown in Fig. 5.This rope, guided by the pulleys e c and ff, drives the pulley and shaftg, and thus the double elevator. 5

The balance-weights p maintain the rope taut to the necessary degree andcompensate for the varying length required should the elevator be inoperation or stowed away.

The pulley at the head of the elevator may also be driven by one of theships winches, or any other convenient source of power.

Hand-winches E E are provided on the deck of the ponton or barge,enabling the respective ends of the pair of elevators to be correctedand readily adjusted to thepositions in which they may be required.

In the case of coal or other such like material it is intended that theelevator should be fed from the lighter or other vessel by manual labor.When used for grain and other suitable matter the buckets or scoops areself-acting.

F represents the boiler on the ponton or barge, driving the winch orengines, which may also be used for its own propulsion, G G being theponton or barge carrying this machinery, H the lighter about to bedischarged, and D the vessel receiving the matter being loaded.

, The elevator boxes, buckets, scoops, or trays may be of various forms,but 'foncoal or material having to be similarly dealt with arepreferably made as scoops or trays and of steel, somewhat as shown inFig. 15, and bars may be placed over them at the lower end of theelevators at such distances apart as will pre vent the admission ofpieces of coal too large to pass into the bunkers. The buckets or scoopsmay work with or without a trough, as shown in Figs. 11 and 15, or in acompletelyinclosed boxing round them.

Figs. 4, 5, and 6 represent the manner in which the suspended frame-workof the elevator may be stowed away for its safe removal when not inoperation, the beams R R supporting it in this position, its weightbeing transmitted through the brackets attached to the elevator-frames.

Figs. 1, 2, and 3 illustrate the method of distributing the coalsimultaneouslyfrom both elevators into deck bunkers by chutes or troughsI I, having as bottoms or traveling on them carrying belts, bands,chains, or scrapers, to which motion is communicated by belts, chains,toothed gearing, or other convenient method. These troughs may be read-I ily detached, so that any number required may be used for distributionof the coal in the various bunkers and the coal thrown otf at anydesired point by the deflecting plates or doors 4". (Shown in Fig.3.) Ifscrapers be used, suitable doors would be placed under the troughs for asimilar purpose.

Figs. 7, 8,9, and 10 show themethod adopted for loadingsteamers or othervessels having the bunkers on their sides, the cross-trough I being usedin Fig. 7 as in Fig. 1. For distribution of coal through the bunkers onthe side next the pon ton or barge, Figs. 9 and 10, a light casing, h,is attached below the head of the elevator, which is temporarily closedat the point at which the distributing-pipe K is attached or suspended.A similar light pipe, is connected to the trough I, Fig. 7, and to eachof these pipes flexible tubes it t' i are attached and led into four ormore bunkers, which are thus fed simultaneously.

The roller-buckets, Figs. 11, 12, 13, 14, 15, are attached to snugs orwings on the malleable or wrought iron or steel links d, the spindles 4passing through these links being preferably of steel of sufiieientstrength to permit of their bearing the weight of the elevator and itsload. These spindles carry at their ends small flanged or groovedrollers 5, acting upon guides 6, these guides being trumpet-mouthed asthey approach and leave the drums, or as they leave them only, roundwhich they travel. The specially-constructed relieving-chain f willprevent serious damage or delay in the event of the possible breakage ofthe main links carry- .ing the roller-buckets. These roller-buckets aremainly so constructed that they may work in the internal curves of anelevator-arm, as illustrated in Figs. 12 and 14., and may be used withor without the relief safety chain or chains f. The curved elevatorsdescribed above may be placedin position either by the ships tackle, acrane, or other convenient means.

Other modifications of the suspended or independent curved elevatorswill permit of their being attached to a portable or fixed gib-crane andfor loading from barges, steamers, or other vessels into railway-trucksor other conveyances or places, or wholly on land.

I am aware that it is not broadly new to arrange elevator-spouts in afloating structure in such manner that they may be raised or lowered atwill; but, so far as I am aware, such spouts have not been heretoforearranged to rotate about the central tower or support, whereby they maybe brought in front or rear of said tower and out of the way when not inuse.

I claim as my invention-- 1. A floating or portable elevator having theelevator-frame suspended from a column or support by ropes or chains insuch manner that it can be raised or lowered and swung horizontallyabout the column or support without moving said support.

2. The combination of the tower or pedestal A, carrying a projectinghead capable of rotation,with suspension-ropes 3, huu g from pulleystherefrom and carrying the elevatorframes 0 O, substantially asdescribed.

3. In a floating or portable elevator, the combination of a motor, 1,carrying pulleys e and f, endless rope 2, actuating the elevator, andtension weight or spring to take up the varying length of rope'requiredas the elevator-frames are raised and lowered.

4.. The mode of driving an elevator by an endless driving-rope passingup the tower or trunk A and round 4 a pulley on the shaft, from whichthe elevator chain of buckets is driven.

5. In a floating or portable elevator, the combination of a centraltower, A, with elevator-frames E, suspended from it in such manner thatthey can be raised or lowered and caused to partially rotate round it,so as to be lowered down and placed fore and aft on the ponton or bargewhen not in use, substantially as described.

6. The elevator-frame O, curved or bent so that its 'end shall becapable of projecting nearly vertically into a hatchway or other space,while the remaining portion or the other end of the frame is at aconsiderable angle with the vertical.

7. The combination of the curved elevatorframe 0, having curved guides6, with the guide rollers or slides 5, working in the guides 6, for thepurposes described.

8. The combination of the spindles 4 with the links (1, the curvedguiding device 5 and 6, and the buckets carried on the spindles 4 bylugs, substantially as described.

9. In combination with a linked chain of buckets, a safety-chain, F,through links of which the spindlesof the chain of buckets pass.

10. The combination of a side trough, such as shown in Figs. 11 and 12,13 and 14, with a chain or band of buckets of an elevator, substantiallyas described.

11. The combination of an elevator for elevatin g coal, with carryingbands or troughs, with IIO adjustable guides for carrying the coal tothe skin of the ship and placed dipping into the various bunkers onboard ship. coal-bunker port.

12. The combination of the elevator G trough k, hopper K, and spout i,for leading JAMES RIGG' 5 the coal into the hopper outside the ship.Witnesses:

13. In combination with an elevator for ele- J. R. MEIHE, vating coals,a spout, 1', arranged outside the A. J. DANIELS.
